Abstract

In this paper we examine the dependence of emf on temperature and concentration in sodium silicate melts in the composition range of 50–85 mole% SiO2 and at temperatures of 600–1400°. Electrochemical concentration cells of the type Pt:O2|Na2O·2SiO2 melt||xNa2O·ySiO2 melt| O2:Pt were investigated. The emf value is determined by the work of transfer of Na2O from one melt to the other, and is a quantitative measure of the basicity of the test melt relatively to the standard melt (Na2O·2SiO2).
